Dynorphin-(1-13), but not dynorphin-(1-9) has been shown to have significant effects on opiate and beta-endorphin-induced analgesia despite not having any appreciable analgesic activity itself. Dynorphin had no effect on Sandoz FK33824 compound-induced analgesia.
Two rat lines selectively bred for ethanol-induced depression of locomotor activity were studied for ethanol-induced analgesia. The effects of ethanol on startle amplitude, extent of overt movements and incidence of audible vocalizations in response to intermittent, noncontingent foot shock. All three responses were dose-dependently depressed by ethanol… (More)
C57BL/6J mice showed dose dependent devreases in locomotor activity with increasing IP doses of ethanol (0.0, 0.75, 1.50 and 2.25 g/kg), while BALB/cJ mice showed dose dependent increases in activity; both strains were equally active with saline. Whether this finding represents decreased CNS responsivity in C57BL mice to ethanol's excitatory effect or… (More)
Using a backward-masking paradigm with a bias-free and ceiling-free psychophysical task, we tested hypnotized and control subjects for speed of visual information processing. Approximately half of each group received visual imagery suggestions in an attempt to influence attention. Imagery produced no significant differential effect. Although an absence of a… (More)
